True, this pair can be tricky but are readily separable given half decent images which, these are not! That said, despite the poor quality images, I am seeing 5 fingers and so would conclude Besra-Crested Goshawk shows 6 fingers.So the legends were true...no one really knows how to tell these birds apart!!

In a word, no.Grahame, does the tail pattern not "rule out" Besra according to other thoughts?
The second bird at a different location had far more appreciable views.
In a word, no.
Second individual is also a Besra. Note, in particular, small bill, slim tarsi and 5 fingers.
Crested Goshawk is an altogether more powerful bird with a larger bill, thicker tarsi which is partially feathered (not visible here) with obviously stronger, more powerful feet. The 'leggings' are finely barred black and the white undertail coverts are typically splayed and more extensive.

Luck.I'm curious how it figures out Besra.
Philosophical question: is 'Luck' a concept applicable to decisions made by a machine?Luck.
Merlin Photo ID is not very accurate. Whenever I've use it it typically gives multiple choices, and it's often heavily biased toward the more common birds.
Philosophically, is luck a concept applicable to anything? Fundamentally no, because everything that happens is caused by something else, whether we can observe it or not.Philosophical question: is 'Luck' a concept applicable to decisions made by a machine?
Hi Qwerty5Philosophically, is luck a concept applicable to anything? Fundamentally no, because everything that happens is caused by something else, whether we can observe it or not.
Anyway, my point was, Merlin didn't really see why the photo was a Besra, and I would be willing to bet that if it were given several more photos of the same bird, it would identify some of them differently. Unless it was using probability to identify the bird, which is something it relies heavily on. For example, if I give Merlin a good photo of a Greater Scaup showing typical head shape, in my area it will always list Lesser Scaup first.
